What are the melting points of solder paste and the components of solder alloys?

Solder paste is generally used as an auxiliary material in many industries. During the process, some things may occur. There are still many types of solder paste and their melting points that people are not familiar with. The composition is also quite important. It is still very helpful to learn more about it for work. The following is an introduction to the composition and melting point by the solder paste manufacturer.

The components of solder paste include tin alloy particles, flux, rheological property modifiers or viscosity controllers, solvents, etc. Different types of solder paste have different components and application scopes. Therefore, when choosing solder paste, one should be extra cautious and truly understand the relevant factors to ensure good quality.

Melting point:

The melting point of solder paste for tin-copper alloy is227℃;

The melting point of the alloy solder paste of tin, silver and copper is217℃;

The melting point of tin-bismuth alloy solder paste is138℃;

The melting point of tin-lead alloy solder paste is183-245℃;

The melting point of tin-bismuth-silver alloy solder paste is172℃;
